Thanks of the query to ATD for an opinion,
The very fact that there is a mass in the abdomen which comes and goes indicates towards the presence of a DIRECT HERNIA. If the swelling is near the groin area it is more likely to be direct inguinal or else most commonly seen in the anterior abdominal wall due to defect and weakness in abdominal muscles and fascial layers.
It is important that a local examination may be performed by a physician along with an ultrasound to confirm the diagnosis and identify the hernial sac and its contents. The treatment is always surgical in form of HERNIOPLASTY which involves reducing the sac contents and strengthening the abdominal muscle and layers with a mesh which disallows any further herniation of abdominal organs .
I hope i have answered your query in detail,
Wishing you good health,
